Barnboy,
This may be a bit late for you as you have fixed yours.
I have same issue with crooked loader.. ~3/4" out.. Same side, left as you sit on tractor.
I spoke with dealer, and he mentioned that they had some tires that were quite a bit different in diameter, one he said was 1.5" in diameter different than the other. (rear, didnt say which type)
Also, he said that they will come out and loosen all loader bracket bolts, and apply down pressure on loader then tighten with pressure on loader.
I will try this, but dont think this will resolve.
On quick tests I did, the front tires were exactly same height.. havent done rears yet.. Need to setup for that.. And I noticed that right loader support was almost 3/16 lower that left.. Which I think is issue.. As someone mentioned before.. Dealer will check with Kubota.. I'll keep you posted..
